TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed January 7, 1904. Serial No. 186.080.

the county of Onondaga and State of New York, have invented certain newand useful Improvements in Type-Writing Machines. of which the followingis a specification.

My invention relates to typewriting machines and more particularly tothe construction and arrange ment of type bars and hangers therefor.

In front strike typewriting machines the pivotal bearings for the typebars are ordinarily arranged below the platen and in a vertical planesubstantially coincident with the front face of the platen so thatparticles of sand, grit, rubber, paper, etc., which drop from the paperat the front face of the platen when an operator is making an erasure,fall upon and in the pivotal bearings of the type bars and mayclog thesame and render the type action sluggish in operation.

One object of my invention is to overcome the above and otherdifficulties heretofore encountered and to provide a type bar and hangerconstruction wherein the bearing or joint between the type bar andhanger is protected against the admission of dust or grit thereto.

A further object of my invention is to provide a 1 simple and efficienttype-bar-and-hanger construction in which the type ears are properlyguided and prevented irom lateral play during the movements thereof; inwhich the bearing is easy and smooth, thus reducing the wear upon theparts to the minimum; and a construction in which the' parts may bereadily assembled.

A still further object of my invention is to provide a constructionwhich affords a close arrangement of the type bars without liability ofconflict between the bars at or in the vicinity of the basket or rest inthe operation of the machine.

A still further object of the invention is to provide an improvedarrangement of restoring springs for the j type bars.

To the above and other ends, which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices to be hereinafter described andparticularlypointed out in the appended claims.

In the accompanying drawings, wherein like referonce charactersdesignate like parts in the various views, Figure 1 is a vertical frontto rear sectional view of sufficient number of parts of a front striketypewriting machine toillustrate my invention. Fig.

2 is an enlarged'fragmentary detail vertical sectionalvie'vy of one formof type bar and hanger, the section end 12 of a link 13 formed of acontinuous wire.

being taken on the line x:r of Fig. Band looking in the direction of thearrow at said line.

Fig. 3 is afragmentary detail side view of the type bar and hangerillustrated in Fig. 2. Fig. 4 is a detail vertical sectional view,corresponding to that illustrated in Fig. 2, of a modified form ofconstruction of type bar type bar segment with some of the hangers andtype bars 'mounted in place. Fig. 7 is a diagrammatic plan view showingthe construction and arrangement of the type bars.

The frame of the machine comprises a base 1, corner posts 2 and topplate 3, which latter supports a' carriage (not shown) that carries aplaten 4, diagrammatically illustrated in Fig. 1. Key levers 5 arepivoted at 6 in the base of the machine and are provided with restoringsprings 7. Each key lever has a sublever 8 which is pivoted thereto at9, and the lower end of each sub-lever is slotted at 10 for cooperationwith afixed fulcrum bar 11 that extends beneath the key levers from sideto side of the machine. upper end of each sub-leveris pivoted to thebent The forward end of each link is bent, as indicated at 14 in Fig. 6,to form a pivot which enters an opening 15 in an ear 16 of a type bar17. A leaf spring 18 has one end bent around and secured to the link 13and bears at its free end against the forward end of the bent portion 14of the link so that the link maybe readily connected to or disconnectedfrom the type bar. The type bars 17 rest at their forward ends upon apad 19 held by a segmental support 19 secured to arms 20 which projectforwardly from a type bar segment 21.

Each type bar is substantially T shaped. in crosssection so as toprovidoa projecting web or flange 22 that extends laterally outwardlyin'opposite directions from the body of the type bar and preferablythroughout, or: substantially throughout, the length of the bar, forpurposes which will hereinafter appear, though certain of the functionsfor which these ledges or flanges are provided may be attained if saidlaterally projecting portions extend forwardly only a short distancefrom the heel or pivotal end of the type bar.

Each type bar is formed or provided with a hardened eye portion 23which, as illustrated in Fig. 2, receives a hardened metal bushing 24that is slightly thinner than the eye of the type bar. This bushing isloosely seated in the eye so that thetype' bar may turn freely thereon.A- hsrdened'type bar hanger 25 has a bifurcated-portion 26 that receivesthe eye .or hub of the type bar.

The bifurcated portion is perforated for the reception of a soft metal.pin or rivet 27 that passes through one of the openings in the hangerand is secured with adrive fit in the bushing 24 and then projectsthrough the other;

opening in the hanger. The hardened bushingis thus connected byafrictional'connection to the pin or rivet The rivet has a head 28 whichis corrugated or roughened at 29 and-seated in a counter-sunk portion 28in one cheek 26, that is likewise corrugated or roughened at 30, whereasthe opposite cheek of the type bar hanger is slightly counter-sunk forthe receptionof the opposite head 3] of the pin or rivet.

In assembling the parts the hardened eye 23 of the type bar, with thhardened bushing seated in place therein ,is insertedinthe bifurcatedportion of the associated hanger and the soft metal pin 27 is projectedthrough the bifurcated portion and through the bushing in the type bar,as illustrated in Fig. 2. Jlhe end of the soft metal pin opposite thehead 28 is then spun down in order to form the head 31 thereon to unitethe type bar and hanger. The head 28 of the rivet is preferably firstseated so as to interlock the projections the bushing, and these partsmay be hardened, so that they will'resist wear indefinitely. Little orno wear will take place between the faces of the eye orhub 23 of the type bar and'the inner walls of the bifurcated portion, f the hanger; butif any wear. should occur it e taken up or compensated for by a furtherspinning or upsetting of the head 31 of the rivet. The

cheeks of the hanger guide and steady the type bar and help preserve the.alinement of the writing.

Each hanger is provided with a depending portionr 32 which is aperturedat 33 to form upper and lower jaws 34 and 35 respectively. The dependingstem of each hanger is seated in'a slot 36 in the type bar segment 21.When the hanger is in place, the shoulder 37,

formed, at the junction between the bifurcated portion and the dependingstem," bears upon the upper face of the segment and supports the hangerin place; whereas the rear face 38 of the stem of the hanger is-adaptedto bear against the rear wall 39 of the slot in which it is received. Ascrew 40 extending fore and aft of the machine is received within athreaded opening 41 in the segment and projects. into the apertureorunthreaded opening 33in the associated hanger and bears at its rearend against the rear inclined wall innam face 33, to force the hanger toits seat and hold the hanger firmly in place, as indicated in Fig. 1.There is Sui ficient space between the screw '40 and the jaws 34 and 35to afford a slight'radial movement of the hanger so, that a tighteningof the screw 40 will properly position the hanger and secure it inposition. It'will be seen that the shoulder 37 and edge 380i each hangerare at substantially right angles to-each other and that th rear wall 39of each slot 36 and the top of the segment are that the shoulders 37,edges 38, walls 39 andtop plate likewise at substantially right anglesto each other and of the segment coiiperateto properlyposition the hangers when they are in the slots. Thus the shoulders 37 and edges '38 onthe hangers will be brought into co o'perati'on respectively with thetop side of the segment and with the walls 39 when the screws 40 aretightened -up. A. hanger may be detached by withdrawing a I will be seenthat each restoring spring extends in the general direction of' thelength of its associated type. bar and is located beneath the same inthe normal position of the bar; that each restoring spring is con,-nected at its rear end to a relatively fixed point below and forward ofbut adjacent to the pivot of its associated type bar and to one of thejaws of theassociated hanger, and at its forward end said spring isconnected to a lug at the bottom edge and about midway of the length ofthe type bar and so that the springswings with-its associated type barand in the plane of movement thereof and gradually expands as the typebar approaches the printing position.

'The construction shown in Fig.4 is similar to tha already described,excepting that the bushing 24 is omitted and the hardened eye 23 of thetype bar has a direct bearing on the rivet or pivot pin which ifdesired, "may be case-hardened. In accordance with. this construction itis necessary to leave'at least one end portion of the rivet sufficientlysoft to upset or spin it over in order to form a head suchas 31' thereonafter the parts are assembled-In the construction shown in Fig. 2,however, the bushing 24 and the eye 10b of the type bar may be hardenedthroughout and the parts may be readily and efiiciently united by meansof the soft-rivet which nevertheless does not take the wear of theparts.

It will be observed that the pivots of the segmental 105 series of typebars'are arranged in a vertical plane substantially coincident with thefront face of the platen and that each type bar is substantiallyT-shaped in cross section so as to 'provide overhangingfiange's or f ace.of the platen, when the operator is making an erasure on thepaper,will. be received on the upper portion of the bar and may be brushed offtherefrom or discharged to the rear of the segment during the upward andrearward printing movements. of the type bars, thus protecting thebearings of the type bars. The flanges 22 preferably extend throughout,or substantially throughout,v the length of the-bar so as to form astiffening or strengthening rib or web for the typebar, in addition to adust cover for the bearing.

From an examination of Figs. 6 and 7 it will be 010- served .thattheslots 36 inthe segmentare arranged at gradually increasing distancesapartifrom the center to the sides of the segment. This'is in order toafford. gradually increasing spacing between the type bars from thecenter to the sides of the system, it being understood that the typebars at the sides of the system should be spaced at greater distancesapart than at the center-in order to provide sufficient clearance forthe type blocks 45, which have a plurality of types thereon andgradually change or increase in their angular relathe system, and thatthe recesses face outwardly.

Furthermore, it will be seen that while the offset or overhangingportion 45 of each type block 45 at the sides of the systcmentcrs orextends to a point within the bend or recess in the next adjacent bar,in the movements of the side bars to and from the printing point thetype blocks or bars will not clash or interfere.

This construction enables the use of a greater number of type :bars in agiven sized segment and notwithstanding the close arrangement of thebars and the fact that the type blocks at the sides of thesegment each'cutsor overlaps the plane of the body portion of ,its

adjacent bar ample space is provided and there is no collision of bars.Without this construction and arrangement, greater spacing between thebars would be required and hence fewer bars could be used within a givenare.

The curved or bent portions of the bars may be variously arranged'in thedifferent bars; thus, certain of the center bars, say ten, may be devoidof the curved or bent portion and the remaining bars be gradually orprogressively curved to greater extents as the sides of the system areapproached, or the curved or bent portions may be of the same sizethroughout, the extent of the curve-in each bar, however, beingsufficient to provide a clearance for the offset block of the adjacenttype bar. V

Each .type bar 17 is preferably forged by a series of operations intothe shape and construction shown,

and holes are then drilled in the type bearing end of ,the bar for thereception of the stem or shank of the type block, in the ear 16 for theconnecting link, and in the hub or heel to form the journal bearing ofthe type-bar.

The eyes or hubs of the type bars are made of an exact size to fitclosely within the bifurcated hangers and inriveting the parts together,care is observed not to cau'seundue pressure between theside bearingportions of the type bar andthe hanger. It is for this reason that therivet is spun over at the end 31 instead of hammered down. It has beenfound in practice that in hammering there is a liability of causing thecheek plates of the hanger to become set against the eye of the type barandhence to bind, but by heading the rivet at iilby a spinningopei'ation with a special tool the pressure on the cheek plates does notcause them to, set or bind agairist'the type bar.

Variouiehanges may be made without departing rrmnithe spirit of myinvention and certain features thereof inay be employed without others.Thus, for

instance, it is immaterial from certain aspects of my invention whetheror not the dust proof feature of the construction be employed, and fromcertain other aspects of my invention the dust proof feature of theinvention may be employed with a joint of any other suitableconstruction. Then again, the recesses 48 may be employed with any styleof bar, type block or type bar bearing, so long as the recessescooperate with the type for the purposes specified.

From the foregoing and from the drawings it will be observed that thehangers have plate-like shanks which fit in radial slots in the segment;that the upper portions of the hangers are forked to provide cheekplates which embrace the sides of the type bars and serve to steady andguide the same and preserve the alinement of the writing, the said checkplates having a close fit to the sides of the type bars without,however, binding upon the same and interfering with the freely swingingmovements thereof; that the type bar isT-shaped in cross section forsubstantially its whole length, which serves to strengthen or stiffenthe bar, the laterally extending flange-like portions being at thetopmost edge of the bar and serving also at the pivotal joint as a coverto exclude dust and particles falling from the platen when erasures aremade; that the flange or web-like portions at the upper edge of the typebar gradually taper from the heel or hub portion of the bar to the typeend thereof, being widest at the hub end of the type bar and narrowestat or near the type end of the bar, thereby not only providing a roofover the type bar joint and strengthening 0r stiffe'ning the barbut-doing this in a manner such as not to add materially to the weightof the type bar and to the touch of the key that operates it; that byprovidingthe bushing or sleeve within the eye of the type bar.

and securing it against rotation by connecting it by a drive fit withthe pin or rivet, the type bar is provided with an enlarged durablejournal bearing; that by providing the pin or rivet with projectionswhich enter depressions in the hanger, or in other words by corrugatingboth the rivet and hanger, the rivet and bushing are prevented fromturning during the vibration of the type bars; that the bonds orrecesses 48 at the free ends of the type bar are offset from the medianline of the bar, although the socket for the stem of the type isarranged practically in said median line; that one of the terminal typeson the type block is arranged substantially over the type shank or stem(and which type is preferably the lower case type) and the otherterminal type is formed on that portion of the block or body of theblank which is offset or overhanging and cuts into or ovprlaps the'planeof the adjacent type bar but which said bar escapes during the action ofthe bar in consequence ofthe said bend or recess.
